Transfer and Proliferation of Breast Cancer
And a few types of cancer, such as thyroid cancer similar to the natural history of breast cancer usually is very long, breast cancer cells, the doubling time for an average of 90 days, from the beginning of a malignant cell, after 30 times doubled, to reach the tumor Lcm diameter of the sphere, which will take seven to eight years. The cause of breast cancer has not yet completely clear, the best way to reduce mortality is early detection and early treatment. In tumor metastasis, surgery and radiotherapy alone can cure the vast majority of cases. Once transferred, the only cure is also positive for a small number of patients, so the natural law understanding of breast cancer. Help choose the best breast cancer treatment programme.
Breast cancer directly to the expansion around, the lymphatic and blood flow. The lymph nodes should be to prevent cancer cells from the primary tumor Yat, the first barrier, if cancer cells through the lymph node barrier is usually recidivism supraclavicular lymph nodes and then penetrated into the blood vein. In addition to the transfer axillary lymph node cancer, also involving the parasternal lymph nodes, for more than the second and third and fourth intercostal, in the first half of breast cancer in the area and areola more so, from here then repeat lymph node cancer. Breast cancer cells may also directly cause vascular invasive metastasis. Side by intercostal thoracic vein into the ipsilateral unknown vein into the pulmonary circulation. Breast deep tissue, breast and chest wall into the vein axillary vein into the subclavian vein and unknown vein, lung metastasis is an important way, the flow of qi intercostal vein and the vein-odd vein, the superior vena cava last Rufei, Ki Venous system through intervertebral vein, vertebral venous plexus, after the group connected with the vertebral vein, vertebral venous system and the vena cava blood flow in intra-abdominal pressure can change the flow of each other, so that some patients in the absence of a superior vena cava ( Such as the lungs) transfer before a skull, spine, Pengu, such as the transfer.
For a long time, people found that breast cancer may have been in attendance at the distant metastasis, despite the clinical was not attending to, this constitutes a conservative implementation of the theoretical basis for chemotherapy. According to today has been able to tumor size, lymph node involvement in the number and variety of other biological characteristics of a preliminary estimate of distant metastases minimal level of risk exists.

Osteoporosis Drugs and Breast Cancer
Raloxifene and breast cancer. There has been a great deal of press interest recently in whether the osteoporosis drug Raloxifene can have an impact on the outcome for breast cancer patients. But what's the evidence? Does this drug reduce the risk of invasive breast cancer?
The recent press reports all related to an extracted subgroup of patients from another research project. That trial was designed to look at heart disease - not breast cancer - but the data was re analysed and extrapolated to look at breast cancer in some of the women who took this medication. The study seems to show that the drug reduces the risk of invasive oestrogen-receptor positive breast cancer in these women, regardless of any underlying risk factors
This was a large study and it backs up other reports which also seem to show a benefit from Raloxifene in terms of breast cancer in women after the menopause. The latter point here may be important - after the menopause.
But is there a place for the medication in the prevention of new breast cancer cases? That answer still remains elusive so we don't know if it should be given to healthy women as a way of reducing breast cancer risk.
Cancer experts are encouraged by the results but warn that this trial was conducted in a particular group of postmenopausal women with heart disease and that therefore the results may not necessarily be applicable to other women - and further research will be needed to confirm the findings. Some commentators have also raised worries that this study was primarily designed to investigate the effects of raloxifene in reducing the risk of heart disease - which it didn't do. They fear that the number of women in the trial might not have been big enough to properly assess breast cancer risks.
Also - before getting too excited about this new data we should remember that any benefit of taking this medication to reduce risk of breast cancer must be balanced against the risk of treatment - in particular the drug is known to increase the risk of thrombosis and an increased risk of fatal stroke was reported in the study.
Lastly - any benefit of taking it in women who already have oestrogen-receptor positive invasive breast cancer was not investigated by this study. We really need to hold fire for a while yet before we can draw any real conclusions.

Breast Cancer - Touchable And Unbelievable
The most common form of cancer in women - which affects about 10% of the world's female population - is still the second most common cause of cancer deaths in women. about 20% of all breast cancer cases ending in death.
This form of cancer is the one considered to have the most serious psychological effects on women. Some specialists say that it happens because this form cancer affects what most women consider to be their symbol of femininity: the breast. Depression is often diagnosed in women who have breast cancer, which makes the treatment even harder.
Risk factors
Many factors are considered to be the possible causes of breast cancer. Contrary to what many people may think, breast cancer also affects men, in smaller proportions - about 1 case in 1000.
Here are some factors considered to be involved in the development of breast cancer:
Age
One thing is for sure about breast cancer: the risks increase with age . Statistics show that for a woman who lives to the age of 90, the risk of getting breast cancer is about 12,5% (or 1 in 8) . However, it's not impossible for young women to have breast cancer and when it happens, the cancer tends to be more aggressive. This is inflammatory breast cancer, difficult to detect because it does not appear in mammography or ultrasound and is often mistaken for mastitis, a simple breast infection .
Genes
Familial breast cancer is rare (less than 5%), but it can happen and it was found to be linked to two different genes. Although this is not a high risk factor for breast cancer, women who have cases of breast cancer among their relatives should have tests more often.
Hormones
The International Agency for Research on Cancer found that women who take combined estrogen-progestogen contraceptives and combined estrogen-progestogen menopausal therapy were at increased risk.
Symptoms and diagnosis
Earlier found, better chances of survival. This is the statement that summarizes the cure for breast cancer and it only makes more important the medical advice that says that women should have a complete check up, including a mammogram and an ultrasound, once a year, especially once they reach their 30s or 40s. A self-examination of the breasts should be done monthly.
Any sign of nodules or lumps found by the woman while doing her self-exam must be taken into account. Most women think that these lumps have something to do with their periods and in many cases they do, but they can also signify the presence of a tumor and that's why the doctor must be told as soon as possible .
The symptoms vary from woman to woman. Some have lumps and some don't. Some women have a white or light-yellow secretion "leaking" from the nipple, some women feel that their breast is tender and swollen. There are those women who feel nothing and these are the most dangerous cases .
The self-exam and the mammogram once a year are the best ways to diagnose breast cancer. If something is found by self-examination, regardless of whether the woman had already had a mammogram that year, another should be done.
Treatment
Medicine has improved a lot in the past few years and the treatments for breast cancer have become more powerful and effective .
There are different options for treatment of breast cancer and doctors can choose the correct one by taking into account the overall health of the woman affected:
- Local or Regional Treatments are directed right to the breast and also to the lymph nodes around the breast.
- Systemic Treatments are directed to the whole body.
- Alternative and Holistic Treatments are important to the person because they include not only the body, but also the mind and spirit as well.
In spite of that, the best treatment is no treatment at all, in other words, prevention.
